Viewing Rollbar Occurrence Data

Rollbar ingests events called occurrences and groups them into single root-cause issues called items. It is usually sufficient to view the data in the item to identify the code culprit of the error, but it can also be helpful to drill down into the individual events to see the exact payload sent from the code to the Rollbar platform.

Viewing your Occurrences

To see an individual occurrence, first click on an item from your Items menu to see the item details menu for a single item with the stack trace and other item information. From there, you can click on the Occurrences sub-menu to view a list of all occurrences.


The "Traceback" sub-menu is shown by default when viewing an item. Click the "Occurrences" sub-menu to view the table.

Once you click this sub-menu, you can see some of the occurrence data in the table, but not all of it. You need to then click on the timestamp shown in the left-most column to view a single occurrence and its data.


Click on the timestamp shown in the left column to view a single occurrence.

The occurrence details menu will have the same information shown for an item, but will also have much more granular information about the key-value pairs received with the given event. You can see the telemetry data for a single event as well since it will vary from one occurrence to the next. Below the usual traceback and telemetry info, you will find a Params table that shows a number of important fields from the occurrence.


The "Params" table and some of its contents.

Continue scrolling down to reach the raw JSON payload. This is the ultimate source of truth for the given event, and shows the full JSON dot-notation to arrive at the given field. The Params table will sometimes remove the prefixes from a given field, so for proper field reference use the dot notation indicated by the JSON payload.


In many cases, it is helpful or necessary to add additional data fields to the Rollbar payload beyond what is automatically captured. These data fields will also be shown in both the "Params" table and the JSON payload.

Deleting an Occurrence

There is also a delete button on the occurrence detail page. This is useful in the event that sensitive information has slipped through in a small number of occurrences, or when other cherry-picking of occurrences is warranted. The delete button is at the bottom of the occurrence detail page, below all of the other tables and information.


Use this button to delete a given occurrence.
